seam filed June 3,

My present invention rel-ates in general to improvements in paper making equipment and has particular reference to an improved means for removing and other foreign substances from beater tubs and transferring them to a cart, trough, or something of that kind for disposal.

As heretofore practiced, therags and other foreign substances have-been removed from 1 the beater tub by more or less laboriousmethodsrequiring the services of individuals and makeshift equipment, so to speak. @ne of the principal objects of my invention is to accomplish automatically What has hereto- 15 fore been carried out manually and thereby increase-the cfliciencyof the existing equip ment with a resultant saving in labor and The preferred embodiment of the inven- 20 tion isillustrated in the accompanying drawing in which:

Fig. I is aview in front elevation of my improved apparatus, which I will hereinafter identify as a selfdumping rag catcher;

i Fig. 2 is a side elevation of the apparatus with the ragl iand'ling carriage thereof in position to collect the rags from the beater tub; i

Fig. 3 is a similar view with the carriage in an elevated dumping or unloading position;

1 Fig. i is a cross section taken on the line Fig. 5' is a detail view in section of one of the rollers for the carriage dumping device.

Referring now to the drawings in detail, 5 and 6 represent a pair of channel members, the spaced positions of which are intended to fit the inside Width of a beater-tub with ledges 7 on the members to rest upon the edge of the tub sothatthe self-dumping rag catcher may be vertically supported over the tub.

The channelimembers 5 and 6 are arranged with tl ieirrecesses facing one another and they are joined at their upper ends by horizontal channels 8 and 9', which lay flush with their narrow sides. Mounted upon the top ofthe frame structure provided by thememhers 5 and 6 and the channels 8 and 9, is a ro atab 1 the 11? e n d p t 1921. Serial No. 196,177.

in the bearings 11 and 12 which in turn are supported by the I-beam supports 13 and 1 1 upon the top of the frame structure. Mounted on the freeend of the shaft to rotate therewith is a flanged cable drum 15. A like drum 16 is mounted to the shaft on theoutside of the bearing 12. The shaft may be driven bya reversible motor (not shown) connected by a belt to a belt pulley 17 which is connect ed to the shaft 10 through areduction gear unit 18;

l Vound upon the drums and 16 are ca bles l9 and 20 the unwound ends of which being connected to the inverted U-hangers 22 and 23 on the rag catcher carriage which is mounted between the vertical side members 5 and 6. The carriage is provided with two sets of wheels or rollers 24 and 25 and the recesses of the channel members 5 and 6 provide tracks for the same sothat the carriage may be elevated and lowered with respect to the frame by the reversil'al-emotor above referred to.

The carriage includes a lower horizontal channel member26 to which the wheels 25 F are mounted by straps 27 and 28 or any other means suitable for the purpose. The upper horizontal frame member 29 carries the rollers 24 and the hangers 22 and 23 for the cables 19' and 20; With this arrangement, the rag carriage is thus mounted to be elevated and lowered between the members 5 and 6 so that the fingers or tines 3O thereon may be lowered into the beater tub for collecting and raising the rags out of the tub.

The fingers are mounted in spaced parallel relation upon the frame so that their curved lower extremities project in front of the apparatus. The mounting for the fingers may be accomplished by providing a series of angle cleats 31', one face of each cleat being secured to the depending flange on the channel member 26 and the other face of the cleats lying flush with and secured" to the sides of the upstanding parts of the finger 30. The upper ends of the fingers are secured to the frame member 29 in any suitable manner' and some of the fingers extend past the member 29 and have transverse openings for the reception of hcriacntal rod The above description explains the construction of the rag catcher. In operation, it is supported over the beater tub as above explained, and, by operating the reversible motor (not shown) in one direction, the carriage may be lowered into the tub by the cables 19 and 20 so that the fingers 30 there may collect a quantity of the rags contained in the tub. By reversing the motor, the carriage may be elevated from the tub with a batch of material carried by the fingers. y In my co-pending application, Serial No. 196,178, filed June 3, 1927, I have shown a similar rag catcher equipped with a spraying apparatus to spray'the material as it is lifted out of the tub. In this case, I have combined the rag catcher with a dumping apparatus so that it thus becomes a self-dumping rag catcher. In this connection, I wish to make it clear that I may use the rag catcher apart from a spraying apparatus or apart from a dumping apparatus or I may use both the dumping apparatus and spraying apparatus in connection with the rag catcher.

IVhen the rags are lifted out of the tub by the fingers of the rag catcher carriage, it has been heretofore necessary to drag them off the fingers by rakes or other improvised manually manipulated means so as to deposit them on trays, carts, or the like.

In accordance with the present invention, I have devised a means of automatically dumping the material at the desired stage in the operation of the rag catcher so that this particular operation may thus be accomplished mechanically without the aid of an individual. As a result, I am enabled to effeet a saving in time and expense in the oporation of this kind of equipment.

l\-Iy improved dumping apparatus preferably comprises a series of dumping arms or the like 33 which are mounted on the rag catcher carriage to normally assume an inactive retracted position behind the curved ends of the fingers 30. Means are arranged to move these arms toward the finger ends so as to push the material off the fingers and upon a tray or cart'or any other device to receive the same. 7

In order that the arms may function in this capacity, I prefer that they be pivotally mounted at their upper ends and arranged to lie parallel with the fingers 30 and even flush therewith. I would ordinarily use about one half the number of arms to that of the fingers so that an arm would lie adjacent every other one of the fingers. The length of the arms exceeds that of the fingers excepting those tingers with which the arms are directly associated. These particular fingers are the ones that engage the horizontal rod 32. This rod provides the pivoted mounting for the upper ends of the arms and for this connection the arm ends are made with openings like the finger ends so that the rod may pass therethrough. The fingers, being made fast to the frame members of the carriage, are not free to move in advance of the carriage like the arms so that their position never changes except in a vertical plane. The arms 30 are suitably braced by oblique angle members which cross one another. The faces of the angles are cut away or slotted at their intersection so as to enable the same to be mounted to the arms in the same plane.

To actuate the arms, each one is connected to a channel member 35 which extends rearwardly and upwardly of the carriage with their opposite end secured to a horizontal member 36. The two outer members 35 are secured to and extend past the member 36 to provide a mounting for the rollers 37 and 38. The rollers in this respect being journaled between the members which support them and the brackets 39 and 40.

Mounted to the back of the upright frame members 5 and 6 and depending downwardly thereof are a pair of oblique channel tracks 41 and 42 for the rollers 37 and 38. These tracks are properly braced by a horizontal angle member 43 and a pair of vertical angle members at and 15.

The lower ends of the tracks 41 and 42 are abruptly turned downwardly so as to confine the rollers in the channels thereof.

Extending from the channel members 35 to the arms 30 are a series of additional bracing angle members 46 which cooperate with the member 35 in imparting the necessary thrust to the arms for dumping purposes. With this arrangement, a thrust is imparted to the arms at spaced distances in their length and develops a decided rigid and positive connection for this purpose. A horizontal rod 47 is also employed to brace the men'ibers 36 and the parts associated therewith.

In the operation of the rag catcher when the carriage is lowered into the beater tub, the rollers 37 and 38 are at the lower end of the tracks 11 and 42. When the carriage is elevated, the rollers 37 and 38 are caused to travel upward on the tracks 11 and 42 and the oblique angle of the tracks results in an outward thrust being imparted to the pivoted arms 33 so that they may move toward the curved ends of the fingers and Wipe or push the material off the fingers. As the carriage is lowered, the arms are returned and reset in their normal retracted position where they do not in any way interfere with the operation of the fingers when collecting another batch.

The operation of the assembly is shown to advantage in Figs. 2 and 3 wherein Fig. 2 shows the arms in a. position that they will assume when the carriage is lowered into the beater tub and Fig. 3 shows the carriage elevated and the arms projected forward at the limit of their active load dumping position.

Obviously those skilled in the art may make mo e-o9 various changes in the details and arrangement of parts v' iout departing from the spirit ant. scope or the invetnion as defined by the claims hereto appended, and I wish therefore not to be confined to the precise construction herein disclosed.
